Oakton Waterproof DO 300 Dissolved Oxygen Meters

IP67 waterproof and dustproof housings float

Perfect for harsh, rugged field conditions
Store 50 measurements with corresponding temperatures and time
Galvanic probe allows you to take measurements immediately

Dissolved oxygen (DO) readings are displayed in mg/L, ppm, or % saturation simultaneously with temperature values. Adjustable backlit display makes it easy to view readings in low light levels. Calibrate at the independent 100% and 0% calibration points to achieve high accuracy over the entire range. Increase reading accuracy by entering barometric pressure and salinity—meters automatically calculate offset. Setup function displays electrode slope, zero offset, and millivolt. Real-time clock stamps stored readings and calibration data with date and time, making it ideal for Good Laboratory Practice (GLP) standards. Additional features include selectable °C or °F temperature units, Hold function, ready indicator, and auto-off for battery conservation.
